Well, you can go with Venus = white planet, Mercury = grey planet, Uranus = greenish planet, Neptune = bluish planet, Jupiter = striped planet.
As you say, though, without a context, none of them convey much and Venus, at least, would just be a circle. Plus there's the question of the context in which someone would want to send little pictures of the planets. This sounds like it would be adding emoji just because. > On Jan 18, 2018, at 10:44 AM, Asmus Freytag via Unicode <unicode@unicode.org> > wrote: > > On 1/18/2018 6:55 AM, Shriramana Sharma via Unicode wrote: >> Hello people. >> >> We have sun, earth and moon emoji (3 for the earth and more for the >> moon's phases).
